FIELD

The present application relates generally to computers and computer applications, and more particularly to computer networks and communication and managing electronic rumor cascades.

BACKGROUND

Electronic mail clients and online social networks provide universal mechanisms to connect people and information in logical and organized ways and enable sharing and processing of information between the users. Examples of mechanisms of sharing and processing information include the inbox, wall, activity stream, timeline, and profile. These mechanisms enable one to rapidly share information with others and gather information from others in the computer networks.

Online social networks provide a substrate for rumor propagation. Recognizing that information received via friends tends to be trusted, online social networks usually allow individuals to transmit information to many friends at once. The trust between friends is impacted based on posts.

However, many rumors, advertising and non-factual cascades far out live the useful life span. False attributions may occur on outdated information that has been circulating online.

DETAILED DESCRIPTION

A system and method of the present disclosure in one embodiment may provide for controlling the sharing of online communication data, for example, posts and messages on the Internet, e.g., via online social network platform, electronic mail (e-mail), and others. The system and/or method of the present disclosure in one embodiment may allow for controlling of the spread of non-factual or harmful information in order to prevent false or harmful rumor cascades.

In one aspect, the system and/or method may determine that a message is going to be shared among users via an electronic communication or computer network, e.g., to be posted to or replied to. The message and the corresponding stream may be analyzed. The message, e.g., posted or replied to message may be queued in a memory device. Responsive to determining that a condition is reached or satisfied, an action may be taken on the message, e.g., posted or replied to message.

Examples of actions taken on the message may include, but are not limited to, forcing a fact check to be performed on the message, removing the posted or replied to message, only allowing a conditional resharing of the message, allowing to share the message only if an expert shared or shares the message also, delegating a reviewer (e.g., another user) to review the message and allowing sharing of the message only if the reviewer verifies the message is true, checking the tone of comments on the message (e.g., in more than only the prior poster's stream) and allowing sharing only if the comments indicate a general agreement or consensus to the message. In another aspect, it may be determined to take no action.

The system and/or method of the present disclosure may work in a computing environment such as collaboration and social systems such as email systems and social networking systems, for example, including asynchronous networks (e.g., where a user may follow another user via an online social network or like platform), synchronous networks (e.g., where users connect to one another and carry on a conversation via an online social network or like platform), instant messaging, wiki, and others.

The system and/or method of the present disclosure in one embodiment may provide for efficient collaboration portfolio, for example, by reducing unnecessary data transmission and storage in collaboration and social systems. By reducing the sharing of rumors, improvements to the computer system or networks themselves are provided in that, for example, there is a less need for storage of data thereby reducing storage or memory space, and that there is less amount of data being transmitted (e.g., less data traffic) in the computer communication networks. The system and/or method of the present disclosure also allow for focusing on high quality data.

The system and/or method may use data associated with online social network members, posts and associated data (e.g., authors, content, readers), actions on the post (e.g., removal, promotion, like, comment, share, @mentions), and post/comments analytics (e.g., sentiment, tone of comments, natural language, downstream shares, upstream shares).

FIG. 1 is a flow diagram illustrating a method of controlling spread or cascade of information transmitted and received via one or more online data sharing platforms and electronic communication network in one embodiment of the present disclosure. The method may be performed by one or more processors. At 102, it is detected or determined whether a message or content is to be shared. For example, a computer module or function may be implemented to hook onto a program method or component of an online data sharing platform (e.g., share methods such as create, update) to detect a message that is to be shared. Hooking may be implemented, for example, by injecting a code or like computer instructions, for example, that may catch or intercept events, function calls, or the like between operating components of the online data sharing platform, electronic communication network, or the like to detect, for example, whether the message is being shared or replied to. Other implementation techniques may be utilized for hooking functionality. Such hooking may detect posts, comments, and actions of users such as removing, promoting, liking, commenting, sharing, @mention-ing. Such hooking function may be implemented to listen to Document Object Model (DOM) changes such as Hypertext Markup Language (HTML) documents, listening to compliance and analytics streams (e.g., social media aggregation application programming interfaces (APIs), and listening to submit and/or post button for postings. The online data sharing platforms may include, but are not limited to, electronic mail, instant message platform, wiki, online social network platform comprising wall, activity stream, timeline, profile.

At 104, the message or content, and corresponding stream, are analyzed. The corresponding stream refers to other messages or content that is in the message stream of the message or determined to be shared, for example, a chain of emails, which the message or content is part of, a chain of posts on a social network web page, which the message or content is part of.

Upon detecting the share on the hook, the method may include retrieving the key identifier for the post which is to be shared. In one embodiment, data attribute such as a correlation identifier, parent-identifier may be used or the DOM may be inspected, to identify or determine parent-child relationship on the messages. The method may also include extracting the natural language of the related posts, and related metadata.

The analysis at 104 may include analyzing the message, its author, content, and readers, analyzing actions on the message (e.g., removal, promotion, like, comment, share, @mention), analyzing sentiment, tone of comments (e.g., by analyzing thread/conversation graph, e.g., checking the tone (sentiment) of the message based on the corresponding stream), downstream shares and upstream shares of the message, and identifies those attributes of the message. The analysis at 104 may also include analyzing by one or more of natural language processing technique, extracting keywords from text of the message and corresponding stream, text analysis technique that develops a regression model associated with the message and corresponding stream. The analyzing, for example, may determine the subject or topic of the message or post, opinion and sentiment about the message or post, and the tone of the comments related to the message or post.

Another example of analyzing may include checking the tone of comments on the message. For instance, the thread or conversation graph of the conversation or message stream involving the message may be analyzed to determine the general sentiment about the quality of the post (message/content). The tone of comments may be checked in more than only the prior poster's stream. If the tone of comments indicates generally agreement, then the message may be shared or posted.

At 106, the message or content is queued, for example, on a memory device or a storage device, for example, coupled to one or more of the processors that may perform the method.

At 108, responsive to determining that one or more criteria is met based on the analyzing, an action may be taken. For instance, based on the analysis, it is determined whether the message or post is a candidate for not sharing or preventing from spreading, and hence, further action is taken. A criterion, for example, may include determining that the content of the message cannot be verified as being credible, for instance, the message content has confidence value below a threshold value that indicates whether the message is likely to be non-factual.

An action may include one or more of forcing a fact check of the message that determines veracity of the message, one or more of removing the message, disabling the message, allowing conditional sharing of the message (e.g., only if the message is posted by an expert on the topic of the message, only after the message is delegated to an identified expert for review and approved), or allowing the message to be shared. In this way, spread of information determined to be non-factual or harmful is reduced or prevented.

An example action may include forcing a fact check. Forcing a fact check of the message may include scanning the message or content and identifying corresponding confidence in the veracity of the message or content. One or more existing techniques may be utilized to determine confidence value associated with the veracity of the content. Forcing a fact check may also include presenting rules (e.g., evidence from a trusted source that may explain why the content may be non-factual, e.g., a corresponding evidence from a trusted source points to a hoax), which state the reason or confidence in the veracity and prompting for secondary approval based on fact check confidence. For instance, the author of the message may be prompted for secondary approval.

Another example of an action may include removing message copies for further transmission (e.g., retweet) or disabling the re-messaging capability or another functionality that would have an effect of propagating the message further to others. For instance, a ‘like’ or another approval functionality further propagates the message of a social network by notifying other users (on their social network page, wall, activity stream or the like) who follow the user who indicated a ‘like’ or approval of the message. In one aspect, the sentiment of the conversation may be analyzed, and the message or content may be deleted from the user's stream. The original poster's conversation may be also deleted. In another aspect, the conversation or the posted message may be hidden from the user's web page, activity stream, wall or the like. Still yet, the continuation of the stream may be disabled, e.g., by locking a conversation. If, for example, the message is in an email, any forwarding or reply to actions may be prevented on that email, e.g., using a lock functionality that may be provided with forum products.

Another example of an action may include conditional reshare. Conditionally resharing may include identifying an expert for a topic of the message. For instance, based on the analysis of the message or content, it may be determined that the topic of the message is directed to engineering. Also, based on the analysis, it may be determined that the author or a poster of the message or content is an expert on engineering. In this instance, the condition that an expert of a topic posted or authored the message associated with the topic is satisfied, and hence the message may be shared.

In another aspect, to perform conditional resharing actions, a message thread may be monitored to determine whether the author or a poster to the thread is an expert. Responsive to determining that the author or the poster is an expert, the message may be automatically shared. Optionally, the expert's post may be highlighted to annotated with another graphically indication. Yet in another aspect, the message may undergo a secondary approval process. Still in another aspect, the message may be sent to delegated to an identified expert for review and approval to share the message. Still in another aspect, trusted advisors in the user's network may be polled to determine their opinion on the veracity of the message prior to posting or not posting for sharing.

In one embodiment, an example of an action may also include doing nothing with the shared post.

At 110, a trust metric may be associated with an author of the message, and the trust metric may be reduced responsive finding that the message or content includes non-factual data. For example, a set of trust metrics may be implemented for users. A user may set a trust metric for each of the user's connections. If the user finds non-factual data in another user's stream, the user may reduce the trust metric associated with that other user, kept by the user. In this way, the user can reduce the user's view of that other user's trust metric. In another aspect, if it is determined that a user has shared without fact checking, that user's trust metric may be reduced. Still yet, if it is determined that a user has previously sent non-factual data, the user's trust metric may be further reduced. The trust metric may be used to filter a view of information. The trust metric may be added responsive to a user sharing information or message without fact checking.

FIG. 2 illustrates a use scenario in one embodiment of the present disclosure. User A, User B, User C and User D are members of an online social network. User A, User B and User C are connected. User C and User D are also connected. User D posts a message to User C. The above-described methodology with reference to FIG. 1 may be performed on User D's message even before it reaches User C, e.g., so that User D's message is prevented from reaching its recipient. In another aspect, the methodology may be performed responsive to User C receiving the message, e.g., so that User C would not be above to further propagate the message to any of User C's connection.

In another embodiment, the methodology of the present disclosure may be activated after a defined number of shares of the original content, e.g., 2 shares. For example User D shares the message with User D's network of connections (which e.g., may include User C). User C shares the message with User B and User A. Responsive to User B and/or User A posting the message for further sharing, the above described functionality for determining whether to prevent further cascade of the message may be activated. As described above, a trust metric may be generated and associated with each user's connection on the social network. In one aspect, the analysis that may include heavy computationally may be performed asynchronously. A confidence measure generated for measuring the veracity of the message may be attributed to a user's trust metric, and the trust metric may be used in subsequent calculations.

The functionality described above may be implemented as a component of a messaging system or a social network system. FIG. 3 is a diagram illustrating system components that may control cascade of information, for example, in an online social network platform or electronic mail system, in one embodiment of the present disclosure. In one aspect, the component 302 may be a plug-in component or a hook that include a capability to intercept function calls, events or the like in the online social network platform or electronic mail system 304. In another aspect, the technique or methodology described above may be implemented integrally with such online social network platform or electronic mail system 304.

In another aspect, the component 302 or the like functionality may be implemented on a client device (e.g., 306, 308, 310), for example, depending on an application type. For instance, for email applications, the intelligence for detecting and performing an action to reduce or prevent further spreading or cascading of information contained in a message may implemented on a client side of the application.

One or more users, for example, who are members of a social network, may communicate via user devices (e.g., 306, 308, 310) over a computer network 312, with other members of the social network, e.g., their connections established on a social network application or server 304. The social network application 304, for example, allows the user to send a message, post a message, like (approve) a posted message and the like, for example for sharing with other members or connections on the social network. The component 302, e.g., detects the message or posted content is to be shared or replied to, for example, by catching or intercepting an event occurring in the social network application 304 as a result of a user performing one or more of sending, posting, liking, commenting, and other actions.

The component 302, e.g., retrieves the post and the related posts in the conversation or message stream. The component 302 may analyze the detected post and related posts and determine the subject or topic of the post, the opinion and sentiment associated with the post, the tone of the comments related to the post. The component 302 may determine that one or more of the subject, opinion, tone is more likely needing an action, and for example, trigger an action on the message.

In one embodiment, the component 302 may establish for the determined subject or topic, that a user (e.g., at 306) is an expert. The component 302 may queue the message, and responsive to that user posting about the message, allow the message to be shared. In one aspect, a monitor waiting on conditional reshare may be established.

In another aspect, the component 302 may be hook into or part of an electronic mail system, and perform the above described functionalities by detecting email messages that are sent, replied to, forwarded, or the like. The components (e.g., 302, 304, 306, 308, 310) shown in FIG. 3 run or execute on one or more processors such as a central processing unit or another processor.
